How to Add Subtitles to the Video That Is Not Yours?


We’ve all been there before: finding a rare YouTube video after a long search and then discovering that it’s not subtitled or captioned. Fortunately, there are many solutions online for easy YouTube video captioning today. The tools for adding subtitles to video content are becoming more common and powerful, thanks to advances in speech recognition and artificial intelligence.

In addition, online content is now made more open-sourced for ease of accessibility and open contribution by just anyone. In this tutorial, we’ll see a few ways you can add subtitles to videos that aren’t yours. But first, we’ll see why you may need to do this.

Why would you need to add subtitles?

Here are three reasons why you should or may need to add subtitles to online videos before starting to watch them:

You may need to watch the videos without sound

Workday has been boring so far because of lack of or insufficient work activities. Then, watching some minutes or hours of videos may seem an option for you. But your HOD must never hear you watching Saint Maud or F9 with the company’s WiFi from your corner!

It is estimated that 92% of consumers watch videos on mobile without sound. Whether at work, traveling, in bed, etc, video subtitles can help you watch videos in discretion or utter silence.

Subtitled videos are more accessible

Closed captioning helps both people with a hearing impairment and those who have insufficient knowledge of the language used in the video. Adding subtitles to video content, therefore, helps in reaching a wider audience effectively.

Video captioning also might have effect on SEO optimization, namely the natural referencing of videos on search engines.

Also, some people watch videos at high speed. Closed captioning also helps understanding in these cases.

So you can listen to the real soundtrack

Some telenovelas come to English-speaking viewers after a post-production process called dubbing, lip-sync dubbing, or voice-over. This eliminates the need for textual translation or subtitling. But that destroys half of the movie or video content’s uniqueness.

You may be planning to capture your video game footage, adding the commentary in textual transcription adds extra spice. The soundtrack is an important part of every movie, and other video contents as the voices of the actors, etc., themselves contribute a lot to the image of their hero. Subtitles will help you follow the story. Therefore, it may be important for you to listen to the original.

Watching movies or TV series with subtitles helps you learn new words and phrases faster. It also allows you to see how words are spelled and thus improve your writing and reading skills.
